I'm in the same boat, trying to lower juice budget lolYours and literally everyone else's as well, sir... lol.
I've gotten help and advice from ecf, youtube, reddit, and even spoke with Joseph from Uwell myself trying to get things sorted.
You are right, all of them at high wattages love their juice, but some are a bit worse than others. I know my Triforce tanks suck it down at least twice as fast as my Crown tanks. And I was led to believe the TFV4's were as bad as my Triforce tanks. With as much as I enjoy hitting these things at 140watts and the insane airflow they have, the budget for juice won't let that happen all day LOL.

I find building coils I can get high power builds which don't use as much juice as standard coils.
Good luck bro!
